Interface PropertyFilter

All Known Implementing Classes:

SimpleBeanPropertyFilter, SimpleBeanPropertyFilter.FilterExceptFilter, SimpleBeanPropertyFilter.SerializeExceptFilter

public interface PropertyFilter

Interface that defines API for filter objects use (as configured using JsonFilter) for filtering bean properties to serialize.

Note that this is the replacement for BeanPropertyFilter, which is replaced because it was too closely bound to Bean properties and would not work with Maps or "any getters".

Note that since this is an interface, it is strongly recommended that custom implementations extend SimpleBeanPropertyFilter, to avoid backwards compatibility issues in case interface needs to change.

Since:

2.3

Method Summary

Modifier and Type	Method and Description
void	depositSchemaProperty(PropertyWriter writer, JsonObjectFormatVisitor objectVisitor, SerializerProvider provider) Method called by BeanSerializer to let the filter determine whether, and in what form the given property exist within the parent, or root, schema.
void	depositSchemaProperty(PropertyWriter writer, ObjectNode propertiesNode, SerializerProvider provider) Deprecated. Since 2.3: new code should use the alternative depositSchemaProperty method
void	serializeAsElement(Object elementValue, JsonGenerator gen, SerializerProvider prov, PropertyWriter writer) Method called by container to let the filter decide what to do with given element value: the usual choices are to either filter out (i.e.

Method Detail

serializeAsField

void serializeAsField(Object pojo,
                      JsonGenerator gen,
                      SerializerProvider prov,
                      PropertyWriter writer)
               throws Exception

Method called by BeanSerializer to let the filter decide what to do with given bean property value: the usual choices are to either filter out (i.e. do nothing) or write using given PropertyWriter, although filters can choose other to do something different altogether.

Typical implementation is something like:

 if (include(writer)) {
      writer.serializeAsField(pojo, gen, prov);
 }

Parameters:

pojo - Object that contains property value to serialize

gen - Generator use for serializing value

prov - Provider that can be used for accessing dynamic aspects of serialization processing

writer - Object called to do actual serialization of the field, if not filtered out

Throws:

Exception

serializeAsElement

void serializeAsElement(Object elementValue,
                        JsonGenerator gen,
                        SerializerProvider prov,
                        PropertyWriter writer)
                 throws Exception

Method called by container to let the filter decide what to do with given element value: the usual choices are to either filter out (i.e. do nothing) or write using given PropertyWriter, although filters can choose other to do something different altogether.

Typical implementation is something like:

 if (include(writer)) {
      writer.serializeAsElement(pojo, gen, prov);
 }

Parameters:

elementValue - Element value being serializerd

gen - Generator use for serializing value

prov - Provider that can be used for accessing dynamic aspects of serialization processing

writer - Object called to do actual serialization of the field, if not filtered out

Throws:

Exception

depositSchemaProperty

@Deprecated
void depositSchemaProperty(PropertyWriter writer,
                                       ObjectNode propertiesNode,
                                       SerializerProvider provider)
                                throws JsonMappingException

Deprecated. Since 2.3: new code should use the alternative depositSchemaProperty method

Method called by BeanSerializer to let the filter determine whether, and in what form the given property exist within the parent, or root, schema. Filters can omit adding the property to the node, or choose the form of the schema value for the property.

Typical implementation is something like:

 if (include(writer)) {
      writer.depositSchemaProperty(propertiesNode, provider);
 }

Parameters:

writer - Bean property writer to use to create schema value

propertiesNode - Node which the given property would exist within

provider - Provider that can be used for accessing dynamic aspects of serialization processing

Throws:

JsonMappingException

depositSchemaProperty

void depositSchemaProperty(PropertyWriter writer,
                           JsonObjectFormatVisitor objectVisitor,
                           SerializerProvider provider)
                    throws JsonMappingException

Method called by BeanSerializer to let the filter determine whether, and in what form the given property exist within the parent, or root, schema. Filters can omit adding the property to the node, or choose the form of the schema value for the property

Typical implementation is something like:

 if (include(writer)) {
      writer.depositSchemaProperty(objectVisitor, provider);
 }

Parameters:

writer - Bean property serializer to use to create schema value

objectVisitor - JsonObjectFormatVisitor which should be aware of the property's existence

provider - Provider that can be used for accessing dynamic aspects of serialization processing

Throws:

JsonMappingException
